Figure 4 is a sectional view taken substantially on the line 44 of Figure 1.

Figure 5 is a perspective-view of one of the keepers.

Referring to the drawings wherein like nu-- merals designate like parts it can be seen that seat sections 'i8. These sections 'l8 have the seat plates 9 suitably secured thereon and the section I carries the swingable hook Ill and the section 8 the eye H, so that when the sections '|8 are folded upon the intermediate section 6 as shown in Figure 3; the section 1 can be hookedly connected with the section 8.

The sections 1 and 8 are connected to the ends of the intermediate section 6 by. hinges l2. The bottom of eachend portion of the. section 6'car- 'ries the notched angle member or keeper l3 which receives the free end'portion of theswingable eye bolt l4 carried by the opposed ends of the sections 1 or,8. A wingnut I5 is' provided on each of the eye bolts l4 and this can be fed inwardly on the eye bolt and against the keeper I3 to hold the corresponding sections 1 or .8 in proper relation with respect to the intermediate section 45 B and against the depending straight portion [6 of the corresponding handle post ll.

Pivotally connected to each of the heads 23 is the upper-end of corresponding legs c-c rising from the base portion (1 of the strap frame 26. Brace members 2'! extend from the frame section 22 and are secured to the legs 0 of the frame 26 by bolts and winged nuts 28. Counterbalancing springs 29 extend downwardly from the intermediate section 6 to connect the cross bars 30 between the legs bb and cc. Numeralx30a' represents a supplemental spring extending downwardly from the intermediate section 6 to connect to the cross bars 3|.

Obviously, by releasing the eye bolt Hi, the sections 1 and 8 can be swung upwardly and onto the intermediate section 6 after the springs 29 and have been released, and subsequent of the brace members 21 can be disconnected so that the stand can be also collapsed. I if While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

' Having described the invention, what is claimed as new is: I

1. An amusement apparatus comprising a stand, a swingable occupant supporting member mounted on the stand, said occupant supporting member being provided with swingably mounted seat sections at the ends thereof, and handle posts adapted to be clamped between the seat sections and the occupant supporting member.

2. An amusement apparatus comprising a stand, a swingable occupant supporting member, occupant supporting seats at the end of the said swingable occupant supporting member, .hinge' structures connecting the seat to the ends of the supporting member, each of the hinge structures including a hinge pin, a handle structure for each occupant seat, each of the handle structures including a frame formation for embracing the corresponding hinge structure and having aportion depending between the corresponding seat structure and end of the supporting member, the hinge pin of the corresponding hinge structure being disposed through the said frame formation.
